Shuttle Foam Test Yields Hole in Wing

Columbia Investigators Fire Foam Insulation at Shuttle Wing, Blowing
Open 2-Foot Hole

The Associated Press

SAN ANTONIO July 7 —
The team investigating the Columbia disaster fired a chunk of foam
insulation at shuttle wing parts Monday and blew open a gaping 2-foot
hole, offering dramatic evidence to support the theory of what doomed
the spaceship.

The crowd of about 100 gasped and cried, "Wow!" when the foam hit.

The foam struck roughly the same spot where insulation that broke off
Columbia's big external fuel tank during launch smashed into the
shuttle's wing. Investigators believe the damage led to the ship's
destruction during re-entry over Texas in February, killing all seven
astronauts.

It was the seventh and final foam-impact test by the Columbia Accident
Investigation Board, and it yielded by far the most severe damage.

The 1.67-pound piece of fuel tank foam insulation shot out of a
35-foot nitrogen-pressurized gun and slammed into a carbon-reinforced
panel removed from shuttle Atlantis.

The countdown boomed through loudspeakers, and the crack of the foam
coming out at more than 500 mph reverberated in the field where the
test was conducted.

Twelve high-speed cameras six inside the wing mock-up and six outside
captured the event. Hundreds of sensors registered movements, stresses
and other conditions.

NASA will continue gathering more information about the poorly
understood pieces that line the vulnerable leading edges of shuttle
wings, board member Scott Hubbard said.

One month ago, another carbon shuttle wing panel smaller and farther
inboard was cracked by the impact, in addition to an adjoining seal.
This time, the entire 11 1/2-inch width of the foam chunk rather than
just a corner during previous tests hit the wing, putting maximum
stress on the suspect area.

In the immortal words of Rosanne Rosanna Dana,

Well now, that's different.

500 MPH!!!!! How did anyone come up with that figure? Seems excessive to
me.
